P traps have to do a lot of work daily and are prime areas for becoming clogged and blocked if not cleaned out regularly. So, it's inevitable that over time they will need replacing. Depending on their condition, P traps tend to last on average around five to 10 years.

Reasons why a P-trap loses water

Expert Recommendations for Sewer Line Cleaning
We recommend homeowners schedule sewer line cleaning every 18 to 24 months to prevent buildup and clogs. Regular cleanings help avoid costly repairs and extend the life of your plumbing system.
Reasons to Caulk Around a Toilet
Moisture Prevention: Without caulk around the toilet base, external water can seep under the toilet, leading to floor and subfloor damage over time. This is especially important in bathrooms with wooden floors, as prolonged exposure to moisture can lead to rot and structural issues.
Blocked Pipes
If your sewage drain is clogged, odors can be released each time a toilet is flushed. Having blocked pipes fixed as soon as possible can help prevent other disasters from happening, such as overflowing toilets. A smelly toilet can be a frustrating problem, but it's not one you have to tackle alone.
In addition, urine and water can get under your toilet and cause further damage. Apply caulking to form a protective coating around your toilet base and combat bad odors.
